The family of elements that I have chosen from the periodic table is family 14. These elements are in the same family because they have similar electron configurations and the same valance electrons. They are where they are on the periodic table because of their ionic charges are the same and the elements on the table go in order according to their atomic weight. Electron configurations:
Carbon-
Silicone-
Germanium-
Tin-
Lead-
|Elements |Atomic radius |Atomic mass |Ionization energy |Boiling point (c) |Melting point (c) |
|Carbon |77 |12.011 |1086.5 |4200 |3620 |
|Silicone |118 |28.0855 |786.5 |3231 |1411 |
|Germanium |123 |72.61 |761.2 |2850 |945 |
|Tin |141 |118.71 |708.4 |2623 |232 |
|Lead |175 |207.2 |715.6 |1746 |327 |
Carbon is present as carbon dioxide in the atmosphere and dissolved in all natural waters. It is a component of rocks as carbonates of calcium (limestone), magnesium, and iron. Silicone is the generic description for an entirely synthetic polymer containing a repeating Si-O backbone. The organic groups attached to the silicon atom from silicon-carbon bonds define the class of silicone. The element germanium is a gray-white metalloid, and in its pure state is crystalline and brittle, retaining its form in air at room temperature. It is a very important synthetic semiconductor material. Tin is a metal and is found in ores, it is not synthetic. Lead is found in ores and is not synthetic.
